From the post
Nice little booster from Tube Amp Doctor. There's still a little bit of confusion on FSB over the correct value of the resistors biasing the base of the transistor, but this should work. Schematic and discussion here. If you'd like a fabricated version of this layout, check out the Strider PCB in the store.
